Welcome to the WPML support forum. I will do my best to help you to resolve these issues.
Please try the following steps after a backup and make sure you are getting the expected result or not.
1) Visit WPML>>String Translation
2) Click on the blue link at the bottom of the page: "Translate texts in admin screens »"
3) Look for the *theme_mods_child* option. Here you should find all the strings associated with your theme options.
4) Check the checkbox for the menu options.
5) Click on the button "Apply"(at the bottom of the page)
6) Now, all your selected strings should appear in the String Translation panel
7) Translate it with French Menu ID
